For safe, trouble-free and efficient operations of machinery and systems onboard ships, it is important that proper maintenance is carried out, records of correct parameters are made, and impurities are prevented from entering the systems.
While the first and second points are a part of routine duties, to prevent impurities from entering the ship’s mechanics, filters and strainers must be fitted to remove any contaminants.
These rules apply to any size of ship, including the Woolwich Ferry, which carries foot passengers and vehicles across the River Thames. The ferry services operates three vessels that each use water from the Thames to cool their engines, which must first be cleaned to prevent any contaminants from entering the system.
Briggs Marine, who operates the service, contacted Croft Filters to help develop replacements for the ferries’ existing filters, which had been installed in the 1960’s.
Croft quickly identified the types of filters that were needed – custom-made double bathtub strainers with easy-to-clean elements – and agreed these would be constructed in stainless steel to prevent corrosion.
Croft re-engineered the filter, which not only solved the drainage problem, but also effectively removed a hands-on function from the process, saving both time and cost.
Nigel Bullen, technical manager of the Woolwich Ferry, commented:
“Operating a busy public ferry service, we could not afford to lose a vessel to any downtime, so we turned to Croft for their filtration specialism.”
Neil Burns, Director at Croft Filters ltd said: :
“Following our consultations with Briggs Marine, we developed a double bathtub filter to increase the open area of the component and the flow of water across it. This has enabled the ferries to filter the river water and cool the engines more quickly and efficiently than before.”
